Leucospilapteryx anaphalidis is a moth of the Gracillariidae family. It is known from Japan (the islands of Hokkaidō and Honshū) and the Russian Far East.
The wingspan is 6-7.1 mm.
The larvae feed on Anaphalis margaritacea. They mine the leaves of their host plant. The mine starts as a linear mine on the underside of the leaf, later it becomes a swollen blotch. The cocoon is made on a fold of the leaf and is elliptical, very elongate and brownish.
